The grounding of the analytical chemistry is in this study intensified about the following methods: elemental analysis, infrared spectroscopy, thermal analysis, X-ray diffraction analysis, mass spectroscopy, nuclear magnetic resonance, gas and liquid chromatography and next separation techniques. Practical using of these methods is addressed to analyses of gas, liquid and solid fuels. Next classical analytical methods of the gas, liquid and solid fuels are also read. Lectures from Analyses of Fuels continue the study of Analytical Chemistry I.
